Body Mass Index In Adults (BMI Calculator for Adults)

Updated:Jul 12,2016

The benefits of maintaining a healthy weight go far beyond improved energy and smaller clothing sizes. By losing weight or maintaining a healthy weight, you are also likely to enjoy these quality-of-life factors too.

BMI stands for Body Mass Index
This is a numerical value of your weight in relation to your height. A BMI between 18.5 and 25 kg/m² indicates a normal weight. A BMI of less than 18.5 kg/m² is considered underweight. A BMI between 25 kg/m² and 29.9 kg/m² is considered overweight. A BMI of 30 kg/m² or higher is considered obese.

Excess weight increases the heart's work.
It also raises blood pressure and blood cholesterol and triglyceride levels and lowers HDL (good) cholesterol levels. It can make diabetes more likely to develop, too. Lifestyle changes that help you maintain a 3-5% weight loss are likely to result in clinically meaningful improvements in blood glucose, triglycerides, and risk of developing type 2 diabetes. Greater weight loss can even help reduce BP and improve blood cholesterol.

To calculate your BMI:

Type your height and weight into the calculator.

Select a status option if you're under 20 years old, highly trained/athletic, pregnant or breastfeeding. If one of these situations applies to you, the BMI may not be the best method of assessing your risk from overweight or obesity.
